INGREDIENTS AND HAZARDS _%_______ EXPOSURE LIMITS 1 4 - 1,1-2,2-Tetrachioroethane, CAS No. 0079-34-5 Ca 100 OSttA PEL (Skin*) 8-HrTWA: 1 ppm, 7 mg/m1 ACGIH TLV (Skin*), 1988-89 TLV-TWA: 1 ppm, 7 mg/m1 This material can be absorbed through intact skin, which contributes to overall exposure. See NIOSH, RTECS (KI8575000), for additional data with references to reproductive, tumorigenic, and irritative effects. Toxicity Data" Human, Oral, TD^: 30 mg/kg Human, Inhalation, TCU: 1000 mg/m1 (30 Mins) Rat, Oral, LDn: 800 mg/kg SECTION 3. PHYSICAL DATA Boiling Point: 295'F (146`C) Melting Point: -47'F(-44*C) % Volatile by Volume: Ca 100 Molecular Weight: 168 Grams/Mole Solubility in Water (%): Insoluble Specific Gravity (H,0 = 1): 1-58658 at 77*F (25*C) Vapor Pressure: 6 Tom at 77T (25'C)* Appearance and Odor: A colorless, nonflammable, heavy, mobile liquid; sweetish, suffocating, characteristic chloroform odor. The odor recognition threshold is reported to be less than 3 ppm. At 77*F (25'C) the concentration of 1,1,2,2-tetrachloroethane in saturated air is approximately 7900 ppm. SECTION 4. FIRE AND EXPLOSION DATA Flash Point* Autoignirion Temperature LEL UEL* Extinguishing Media: * 1,1,2,2-Tetrachloroeihane does not burn. Use extinguishing agents that will put out the surrounding fire. Unusual Fire or Explosion Hazards: None reported. Special Flre-llghting Procedures: Wear a self-contained breathing apparatus (SCBA) with a full facepiece operated in the pressure-demand or positive-pressure mode to protect agamst the effects of the nearby fire. SECTION 5. REACTIVITY DATA StabUlty/Polymerization: 1,1,2,2-Tetrachloroethane is stable in closed containers during routine operations at room temperature. Hazardous polymerization cannot occur. Chemical Incompatibilities: Hazardous reactions between 1,1^2-tetrachloroethane and 2,4dinitrophenyl disulfide, nitrogen tetroxide, chemically active metals such as potassium; and strong caustics such as potassium hydroxide, sodium, sodium-potassium alloy, hot iron, aluminum, and zinc in the presence of steam are reported. Conditions to Avoid: Prevent exposure to the incompatible chemicals listed above. Contact with water causes appreciable hydrolysis that will degrade and decompose this liquid. Hazardous Products of Decomposition: Thermal-oxidative degradation of 1,1,2,2-tetrachloroethane can produce highly toxic gases such as carbon monoxide (CO) and oxides of chlorine (CIOJ. SECTION 6. HEALTH HAZARD INFORMATION Carcinogenicity: NIOSH lists 1,1,222-tetrachloroethane as a carcinogen. Summary of Risks: 1,1^2-Tetrachloroethane is absorbed through intact skin in significant amounts; one human fatality has been attrib uted to this route of exposure. This liquid is considered to be one of the most toxic of the common chlorinated hydrocarbons, particularly with respect to the liver. Severely acute exposure causes depression of the central nervous system (CNS), which can cause death within 12 hours. Medical Conditions Aggravated by Long-Term Exposure: None reported. Target Organs: Skin, eyes, respiratory system, CNS, gastrointestinal system, liver, and kidneys. Primary Entry: Inhalation, skin contact/absorpuon. Acute Effects: The initial symp toms of exposure are laenmation, salivation, and irritation of the nose and throat; continued exposure can lead to nausea, vomiting, and narcosis: Also, low blood pressure and cardiac rhythm abnormalities; respiratory depression; nausea, vomiting, bums of the esophagus, and diarrhea; and anesthesia with dizziness leading to loss of consciousness and coma; plus possible transient liver and kidney changes. Chronic Effects: The two sets of manifestations are (1) malaise, drowsiness, decreased appetite, then nausea and retching, a bad taste m the throat, consupation, headache, pale stools, jaundice, and dark unne, as well as mental confusion, stupor, and coma; and (2) hand Copfrtctt 19U t?

HEALTH HAZARD INFORMATION, cont. tremors, sensation of deafness, numbness in hands and feet, a decrease in reflexes, headache, and nausea. FIRST AID: Eyes. Immediately flush eyes, including under the eyelids, gently but thoroughly with flooding amounts of tunning water for at least IS minutes. Skin. Rinse the affected areas with flooding amounts of water, then wash it with soap and water. Inhalation. Remove the exposed person to fresh air, restore and/or support his or her breathing as needed. Have qualified medical personnel administer oxygen as required. Keep the exposed person warm and at rest until medical help is available. Ingestion. Unlikely. Should this type of exposure occur, give the exposed person 3 glasses of water to drink and induce vomiting, then repeat this procedure. Get medical help (in plant, paramedic, community) for all exposures. Seek prompt medical assistance for further treatment, observation, and support after first aid. Note to Physician: Workers exposed to this liquid should be evaluated with a full battery of tests for the liver, kidneys, and CNS systems, as well as the blood. SECTION 7. SPILL, LEAK, AND DISPOSAL PROCEDURES Spill/Leak: Notify safety personnel, evacuate unnecessary personnel, and provide adequate ventilation. Cleanup personnel must be prop erly clothed and equipped to protect the skin and eyes against any contact with the liquid as well as inhalation of its vapor (see sect 8). Vacuum the spilled 1,1^2-tetrachloroethane and pump it into suitable containers for disposal. Waste Disposal: Contact your supplier or a licensed contractor for detailed recommendations. Follow Federal, state, and local regulations. OSHA Designations Listed as an Air Contaminant (29 CFR 1910.1000 Subpart Z). EPA Designations (40 CFR 3024) RCRA Waste, No. U209 CERCLA Hazardous Substance, Reportable Quantity: 1 lb (0.454 kg), per the Clean Water Act (CWA), 307 (a); and the Resource Conservation and Recovery Act (RCRA), 3001. SECTION 8. SPECIAL PROTECTION INFORMATION Goggles: Always wear protective eyeglasses or chemical safecy goggles. Where splashing of this liquid is possible, wear a full face shield. Follow OSHA eye- and face-protection regulations (29 CFR 1910.133). Respirator: Use a NIOSH-approved respirator per Genium reference 88 for the maximum-use concentrations and/or the exposure limits cited in section 2. Follow OSHA respirator regula tions (29 CFR 1910.134). For emergency or nonroutine operations (spills or cleaning reactor vessels and storage tanks), wear an SCBA. Warning: Air-purifying respirators will not protect workers in oxygen-deficient atmospheres. Other: Wear impervious gloves, boots, aprons, gauntlets, etc., to prevent skin contact with this liquid. Ventilation: Install and operate general and local ventilation systems powerful enough to maintain airborne levels of this material below the OSHA PEL standard cited in section 2. Local exhaust ventilation is preferred because it prevents dispersion of the contaminant into the general work area by eliminating it at us source. Consult the latest edition of Genium reference 103 for detailed recommendations. Safety Stations: Make emergency eyewash stations, safety/quick-drench showers, and washing facilities available in work areas. Contaminated Equipment: Contact lenses pose a special hazard; soft lenses may absorb irritants, and all lenses concentrate them. Do not wear contact lenses in any work area. Remove contaminated clothing and launder it before wearing it again; clean this material from your shoes and equipment. Comments: Practice good personal hygiene; always wash thoroughly after using this material and before eating, drinking, smoking, using the toilet, or applying cosmetics. Keep it off your clothing and equipment. Avoid transferring it from your hands to your mouth while eating, drinking, or smoking. Do not eat, drink, or smoke in any work area. Do not inhale !, l,Z2-tetrachloroethane vapor. SECTION 9. SPECIAL PRECAUTIONS AND COMMENTS Storage/Segregation: Store 1,1^2-tetrachloroethane in closed, airtight containers in a cool, dry, well-ventilated area away from incom patible chemicals (see sect- 5). Special Handling/Storage: Provide storage areas with adequate ventilation to prevent concentrations of the vapor from building up beyond the occupational exposure limits cited in section 2.
